Export GeoJSON

Download a GeoJSON dataset as GeoJSON, KML, CSV, or Shapefile (zip).

The Export item is added to the list ⋮ menu when the layer has a GeoJSON source or a data-management sibling. Raster / vector-tile layers hide it.

Needs createDatasetRegistryPlugin() so the submenu renders.

Formats

Format	File	Notes
GeoJSON	.geojson	Always available
CSV	.csv	Properties + geometry JSON column
KML	.kml	Needs optional peer tokml
Shapefile	.zip	Needs optional peer @mapbox/shp-write

Data comes from data-management.list() when that node exists; otherwise from the GeoJSON source (getData(), or a URL that is fetched).

Built-in menu

createDatasetPartListViewUiComponentBuilder('Cities')
  .setColor('#ff6b6b')
  .build();

Turn off: .configDisabledExport(), or menuContext: { disabledExport: true }.

Custom formats / filename:

import { createMenuItemExportGeo } from '@hungpvq/vue-map-dataset';

list.addMenu(
  createMenuItemExportGeo({
    formats: ['geojson', 'kml'],
    filename: (layer) => layer.getName(),
  }),
);

If you add it yourself, also call .configDisabledExport() so the default item is not duplicated.

Call without a menu

import { exportDatasetGeo, getDatasetFeatureCollection } from '@hungpvq/vue-map-dataset';

const fc = await getDatasetFeatureCollection(list);
await exportDatasetGeo(list, 'kml');
await exportDatasetGeo(list, 'shapefile', { filename: 'cities' });
await exportDatasetGeo(list, 'csv', { collection: fc, filename: 'cities' });

Pass collection to export a FeatureCollection you already have (the attribute table Export does this for the visible rows). The list ⋮ Export item and the table toolbar share createExportGeoSubmenu → exportDatasetGeo.

Vue / React

No extra control. Mount LayerControl + createDatasetRegistryPlugin(). KML / Shapefile need:

npm install tokml @mapbox/shp-write
